You can resolve these issues by isolating the voice traffic onto a separate VLAN.
The switch port that the phone is connected to would be configured to have
separate VLANs for carrying:
Voice traffic to and from the IP phone (auxiliary VLAN, on the Cisco Catalyst
•
6000 series, for example)
Data traffic to and from the PC connected to the switch through the access
•
port of the IP phone (native VLAN)
Isolating the phones on a separate, auxiliary VLAN improves the quality of the
voice traffic and allows a large number of phones to be added to an existing
network where there are not enough IP addresses for each phone.
For more information, refer to the documentation included with a Cisco switch.
